| Abstract | The optical spectra of aqueous suspensions of tetracene (obtained by heating crystals in water) and 9,10-bromoanthracene (obtained by mixing alcoholic solutions of the compound with water) were studied. Both optical pictures were turbidity spectra related to the formation of comparatively large colloidal light scatterers superimposed upon the absorption bands of light hydrophobic ensembles; the absorption bands of free acene molecules were absent. An analysis of the optical spectra and the construction of models with the use of molecular mechanics programs led us to conclude that light hydrophobic ensembles were molecular dimers comparatively stable in the aqueous phase because of the formation of hydration capsules around them. A model of spontaneous dispersion of crystalline tetracene in water under heating was suggested. The model included the stages of the emergence of tetracene molecules from the surface of crystals and their hydration in water layers adjacent to crystals, formation of molecular dimers on the surface of crystals, and diffusion of dimers into the bulk phase, where they experienced clusterization with the formation and sedimentation of fairly large light scattering colloidal particles. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
